After the latest patches for the Beta Client, blizzard changed some small thing that had a big impact on what we where doing.
Since the last update AI-Art has been remade twice because off new things showing up.
The latest patch change something to 1 texture, that showed up nearly everywhere and made us go over it again.
So the top square has been replaced with the rounder one. Shadows have been added. So just wait a little longer and there will be a huge update.
